IBM's Brain-Mimicking Chip Has 256 Million "Synapses"

IBM has created a computer chip that mimics the functioning of the human brain, opening wider the possibility for a vast Internet of Things.

What's the Latest?

IBM has created a computer chip that mimics the functioning of the human brain, opening wider the possibility for a vast Internet of Things. Such a network would consist of a variety of machines, from refrigerators to industrial equipment, that could measure data and report their results to a central aggregator. The new IBM chip, dubbed True North, has 4.5 billion transistors woven onto 4,096 "neurosynaptic cores" which creates the equivalent processing power of 256 million synapses. When IBM stitches 16 of these chips together, the resulting power offers the equivalent of 16 million neurons and 4 billion synapses.

What's the Big Idea?

While the brain-mimicking chip is extremely powerful, it is not meant to replace the standard processor. What sets it apart is its ability to work on different lines of computation simultaneously, like the brain does, rather than in a linear fashion (to which current processors are quite well-suited--far better than the brain, in fact). The chip is also very efficient like the brain, requiring very little power—"only 70mW during typical operation, which is an order of magnitude lower than what standard processors would require to execute the same operations."

Politics & Current Affairs
  • Despite being widely known for his leadership role in the American civil rights movement, Martin Luther King, Jr. also played a central role in organizing the Poor People's Campaign of 1968.
  • The campaign was one of the first to demand a guaranteed income for all poor families in America.
  • Today, the idea of a universal basic income is increasingly popular, and King's arguments in support of the policy still make a good case some 50 years later.

Why I wear my life on my skin

For Damien Echols, tattoos are part of his existential armor.

  • In prison Damien Echols was known by his number SK931, not his name, and had his hair sheared off. Stripped of his identity, the only thing he had left was his skin.
  • This is why he began tattooing things that are meaningful to him — to carry a "suit of armor" made up the images of the people and objects that have significance to him, from his friends to talismans.
  • Echols believes that all places are imbued with divinity: "If you interact with New York City as if there's an intelligence behind... then it will behave towards you the same way."
